Specification of Letters Patent.

HE FLANGES OF CAN I Patented Jan. 13, 1920.

Application filed January 29, 1916. Serial no. 75,038.

the Flanges of Can Ends, of which the following is a specification.

The present invention relates to a machine for cutting ring liners froma continuous web or blank, and applying the same to the flanges ofpositioned can ends,

and has for its object'the provision of a machine for this purpose,simple of construction, and which necessitates the use of relatively fewmoving parts, particularly those to which reciprocating motion must beimparted.

To this end the invention comprises broadly associated instrumentalitiesfor cutting a disk blank from a continuous web, for cutting a ring linerfrom said blank, and for applying said ring liner to the flange of a canend in axial alinement therewith, interworking in timed relation withdevices for holding and carrying the blank and ing liner, and means forpositioning a can end in proper relation thereto for the reception ofsaid liner.

In order to more fully comprehend the invention, a preferred embodimentof which is hereinafter described, referenceshould be had to theaccompanying sheets of drawings wherein Figure 1 is a front elevation ofthe complete machine.

F i 2 is a vertical section taken. on the line of Fig. 1,.and viewed inthe direction of the arrows.

Fig. 3 is a horizontal section taken on the line y of Fig. 1, and viewedin the direction of the arrows.

Fig. 4.- is a detailed vertical section, enlarged, taken on the line 88of Fig. 3, and viewed in the direction of the arrows.

Fig. 5 is a detailed vertical section, enlarged, taken on line 5 2? ofFig. 3, and viewed in thedirection of the arrows.

Fig. 6 is an enlarged detailed verticai section taken on the line a-a ofFig. 3, and viewed in the direction of the arrows:

Fig. 7 is an enlarged detailed vertical section taken on the line w w ofFig. 3, and viewed in the direction of the arrows.

In the drawings, the reference numerals 1 designate the spaced uprightside members of a suitably constructed supporting frame, which sidemembers are united together and held in spaced relation by a crossmember 2 at their lower portions, a similar cross memher 3 at theirupper portions, and between said cross members by vertically disposedwibs 4 and 5, and a horizontally disposed ta ie 6.

Power for operating the moving parts of.

the machine is applied to a horizontal shaft '7, rotatably mounted inthe upper portion of the frame, by means of a belt pulley 8 fixedthereon. It is to be understood, however, that any suitable form ofdriving means may be employed. The horizontal drive shaft 7 transmitsits rotary motion by means of a vertical shaft 9, Fig. 1 of thedrawings, to a second horizontal shaft 10 suitably journaled in thelower portion of the frame. latod that they rotate in unison.

The upper shaft 7 carries a crank 11, Figs. 1 and 2 of the drawings,which imparts vertical reciprocating motion, through a connecting rod12, to a head 13, slidably mounted upon the upper web 5 of the frame,and retained in position by suitable guides 14. This head 13 has anenlarged lower portion 15, which carries a series of depending dies,shown at 16, 17 and 18 respectively, in Fig. 1 of the drawings, andwhich will be .more fully described hereinafter. In a similar manner thelower shaft 10 carries a crank 19, which imparts vertical reciprocatingmotion, through a connecting rod 20, to a head 21. slidably mounted insuitable guides 22 upon the lower web t of the frame. Said head 21carries upon its upper end a dle ring 23, Figs. 2 and 5 of the drawings,adapted to coact with the die 17 through an opening 6 in the table 6,for a purpose to be later set forth.

A horizontally disposed turret 24 is rotatably mounted above the table 6and beneath the upperreoiprocating head 13. Said turret is formed with aplurality of vertical openings therein, there being four of said Saidshafts 7 and 10 are so reby structural considerations.

' 28, adapted to mesh with a similar gear 29 horiz the. turret 2% i ,7.thus carrying the dish 43 from the position 'ri to the position B,-

fixed upon the lower end of a second vertical shaft 30. This lattershaft 30 is rotated intermittently from the lower horizontal shaft 10,by means of coacting mutilated worm gears 31 and 32, in such relationthat for every complete revolution of the hori zontal shafts and 10, theturret 2% is turned to bring one of the openings therein into axialalinement with the die 16, that is, in the particular machine hereinillustrated,

one quarter of a revolution.

The web 33 of paper or other material from which the mug liners are tobe. cut is shown in Figs. 3 and t of the drawings, as

carried upon a spool or roll 34, and led in a ntal direction across themachine 11nniedrately above a plate which is secured at 36, to the table6, extending over the turand provided with an opening 37 in which ismounted a stationar die rin 38 of size suitable to react with thereciprocating die 16, as shown in Fig. lof the draw ings. The web 33 isthen passed between a feed roller 39 and an idler roller d0, the formerbeing intermittently rotated by the turret shaft 27 through the agencyof the short geared shafts L1 and L2, to intermittently feed said webthrough the machine at the proper rate. 4

It will be by reference to Fig. f of the drawings, that the die 16',being forced down into the coacting stationary die ring 33, cuts acircular disk from the inter-- ml) 33, and deposits said disk on the g hs disk cutting operation, said s ationary. immediately following the rrsing of the die 16, however,

s moved one step fmw/ard,

V rig. 3 of the drawlngs, in which latter position it is in axialalinement with the upper reciprocating die 1'? and the coacting lowerreciprocating die ring-23,Figs. 2 and 5 of the drawings.

The upper die 17 is encircled by a stripper ring -14, which has alimited range of vertical movement thereupon, and which is normally heldat the lowermost limit of said movement by springs 45. The upper die 17and the lower die ring 23 are moved simultaneously in oppositedirections by their re- 3 spectlve; operating mechanisms hereinbeforeflange 26 within the opening 25 in is linden-stood, of course,

die and die ring 17 and 23 are then sep-.

arated, and the stripper ring removes the cut ring liner 16 from the die17, and leaves the same deposited on the shoulder 26 of the opening ofthe turret 24E. Said turret 2-fl is then advanced another step, to bringthe opening 25 with the cut ring liner a6 therein to the position C inFig. 3 of the drawings, where it is in vertical alinement with the thirdupper reciprocating die 18.

Fixed upon the upper end of the vertical intermittently rotated shaft30, above the table 6 and underlying a portion of the turret 2a, is asecond turret 18,Figs. 1, 3, 6

and 7 of the drawings, formed with circular lower continuously rotatingshaft 10, and a lever Said feed slide 53 moves the lowermost freed canend from the holder through one of the radially disposed grooves orslots 56 in the under side of the turret 13 until said can end lieswithin one of. the openings +29, at the position D in Fig. 3 ,of thedrawings.

A circumferential groove 57 is also formed in the under side of theturret e8, which lies over a circular guide rail 58, secured to thetable 6, and formed with air opening 59 adjacent the holder 51, throughwhich theends are pushed by the, feed slide 53.

Thus it will be seen that a can end 50, seated within one of thecircular openings 49 in the turret 48', will be carried around over thesurface of the table 6 bythe movement of said turret and will heprevented from escaping through the slot 56 by the guide rail 58.

In this manner a can end 50 is carried to the position C, Fig. 3 of thedrawings, where it rests upon the table 6 below and in verticalalinement with the ring liner 4E6 which is supported within the opening25 in the turret 24:. During a period of rest of both turrets, the upperreciprocating head 13 moved downward to bring the assembling (lie 18down through the openings 25 and 49 in theturrets 24 and 48respectively,

and to force the ring liner 46 from its seat 26 in the opening 'downonto the flange of the alined can end 50, as shown in Fig. 6 of thedrawings. 7

At the next step in the rotation of the turret 48, the can end 50, withits assembled ring liner l6, is carried to the position E, Fig. 3 of thedrawings, at which point there is an opening in the table-6, throughwhich said lined can end drops, and from which it is carried as by achute 61, Figs. 3 and 7 of the drawings, to a suitable place of depositnot illustrated.

It is to be noted that in the preferred form of the constructedapparatus, the

I blank cutting die 16, the ring cutting die 17 every stroke of saidhead, a blank is cut from the web at A in Fig. 3 of the drawings, a ringliner is cut from a blankat B, a ring liner is applied to a can end atC, an unlined I can end is fed from the holder at D, and a lined end isdischarged from the machine at E. The die ring 23, carried by the lowerreciprocating head 21, coeperates only with the ring cutting die 17 atthe position B.

The invention has hereinbeen described and illustrated in its preferredform. I do not wish to limittmyself thereto, however, for the reasonthat many changes may be made in the machine as ilustrated withoutdeparting in any manner from the spirit of the invention, and it istherefore my wish to be understood. claiming'the invention as broadly asthe art will permit.
